back up the back up..

This is the story, i dvd shrink does its magic and i can back up, but then again, i cannot back up the copy. dvdshrink gives an error.

i cannot even copy the copy dvd with Nero. so why the hell does that happen.
- i cannot copy the copy.
- i can copy but my dvd rom is messed up so it doesnt read it.
- dvd shrink does not back up the copy.
- or something else that i dont know that keeps pissing me offf....

ok I got an original movie...copied it both normal and deep analysis back up...but i still couldnt copy the copy...

Nephilim, i will sound stupid i know but how can i reburn the video_ts as i only know to put the dvd in the rom and blank inthe burner and just back up...can you give some details if you can?...and how can be the copy be a bad quality one? how can i make sure that it is not bad quality?...

michigan, thanks for help, can you tell me what you mean by different media, if it is different movie, i have already used a good dvd to back up..or if it is a different burning tool other than shrink or Nero, can you recommend me another one?...

another general question my biggest tv at home is 51cm so just wondering if i watch the shrinked movies on a bigger screen tv say 148cm would it be so bad if the compression is below 70 %?

wow, too many questions :} sorry guys i am really into this and wanna get the best ican..

Here's a little guide by Scubapete:Pete's Nero guide
Do not use Nero Wizard.
When you open Nero Burning ROM, you will be at the “New Compilation” window. Directly under the title “New Compilation” is a choice block to choose either DVD or CD, choose DVD. Directly under that click on the DVD Video Icon. Then click “New” in the upper right corner of that screen, NOT the main screen.
You now are in the DVD Video window. In the left screen, click VIDEO_TS. In the File Browser screen, 3rd from the left, trace your path to the VIDEO_TS folder, the one you made earlier holding all of your files and click on that folder. All of your VIDEO_TS files are now opened in the right screen. Click on the top file, hold down the “Shift” key and then click the bottom file thereby hi-lighting the entire column of files. Click and (holding the left mouse button down) drag the entire column of files to the open screen, second from the left.
Now click the icon on the task bar that shows a match on a disc, and then click “OK” and now shout out, “Burn Baby, BURN !” one more time, let me hear you say it, “Who’s your Daddy Now ???” Guess what my Friend ? You are done !!!

?...and how can be the copy be a bad quality one? how can i make sure that it is not bad quality?...

If you use decent media, any disc copy software will work. Roxio or Nero has this. Shrink and Decrypter will also work (if the source can be read/ripped ... which is why it helps to use quality media to start)
